Efforts to implement structural reforms and root out corruption have stalled.

Cronyism and oligarchic influence remains rampant.

The economy is mired in crisis.

And the pro-Western government in Kyiv is rapidly losing allies and hanging on by a thread.

Given all this, it's easy to succumb to Ukraine fatigue, to throw up your hands and lament the failure of a democratic revolution.

It might be easy, but it would be a grave mistake.

It would be a mistake because what happens in Ukraine is vital for the survival of the post-Cold War international order. If Ukraine fails, it would prove -- in Moscow and elsewhere -- that might makes right.

But more importantly, it would be a betrayal of those brave Ukrainians who risked their lives on the Maidan two years ago for the sake of a better future.

Ukrainians are the first nation in history to shed blood for the idea of Europe.

And they deserve better.
